To calculate the work done by each person, we use the formula Work = Force * displacement.
Person 1: Work = 2 N * 10 m = 20 J
Person 2: Work = 10 N * 2 m = 20 J
Person 3: Work = 2 N * 5 m = 10 J
Person 4: Work = 5 N * 2 m = 10 J
Therefore, Person 1 and Person 2 do the most work, both with a work of 20 J. The answer is e.
